Abstract:
AT2024biz is indeed a SN, possibly type II around max, needs re-confirmation

We observed AT2024biz on Feb. 7, 23h00 UT, with Mistral on the T193 at Haute-Provence Observatory, through a temporary opening in  thick clouds. The SN is clearly visible, and brighter than 18th mag. With a redshift of 0.02449 for the Wise host galaxy (from NED), this gives an absolute magnitude around -17 or brighter. A poor quality, low S/N spectrum with Mistral (spectral resolution 700, range 400-800nm), shows a featureless continuum, hence possibly indicating a type II SN around maximum. A better quality spectrum is required to consolidate the classification.
